This invention relates to mechanism pro videdfor feeding fillers into a machinewhich is designed to apply cases to the fillers, of

the type illustratedin'United States Patent No. 1.765.349, June 17, 1930.

The upper s'ur-J face of the supporting baris usually convex and it exten dsfrom the front of the machine nearly to the inner end of the separator plate which is above it. a i f I i" The supporting bar is fastenedin a chairpahle of being adjusted vertically by screws I 14 forthe purpose 'of'raising or lowering the bar according to the WldthiOf thefillers which 5' ing the supportings e ectionofthe separator plate i V are to be fed, as specified in the patent referred to.

On the upper edges of the channel member are transversely movable slide plates 15, to the inner edges of which the guide rails 16 are fastened. These guide rails extend in the channel member parallel with the supporting bar and retain the lower edges of the fillers from separating as the fillers are fed along the supporting, bar. The slide plates may be moved in and out in order to adjust the space between the guide rails according to the thickness of the fillers, by rocker arms 17 fastened to shafts 18 which are capable of being given rotary movements by rocker arms 19 that engage nuts 20 on screws 21.

Adjustably mounted on the slide plates at the front are guide blocks 22 adapted to direct the lower edges of the tillers when they are passed by the operative into the machine. Filler guiding walls 23 may also be attached to the slide plates adjacent to the initial filler osition, which guiding walls are adapted to removed when the fillers are of narrow width.

Pivoted on top of one of the slide plates is a gauge 24. A spring 25 yieldingly retains the gauge with its inner end extending into the path of the fillers. The operative pushes the fillers into the machine past the gauge and then draws them back against it so that they will be located over the separator plate and on the supporting bar in correct initial position.

A gauge 26 is pivotall mounted on the slide plate and retained y a spring 27 so that its inner end that extends into the path of the fillers will yield when a filler is fed past it but will prevent the filler from being accidentally drawn backward by the return movement of the means which feeds it from second position to third position on the supporting bar and over the separator plate.

The supporting bar and the slide plates with the guide rails and the gauge stops being all carried by the channel member are raised and lowered together to adjust them according to the size of the fillers to be fed.

As in the machine of the patent referred to the present feed has two shafts 28 and 29 that extend parallel with each other and with the supporting bar and separator plate, the shaft 28 being capable of rotary movements and the shaft 29 being held against such movements. Fastened to the shaft 28 is a. toothed segment 30 engaged with which is a toothed segment 31 that is oscillated at the required times by suitable mechanism (Fig. 7).

The edges of the fillers placed by the operative over the separator plate are engaged and pushed from initial to second position (indicated by dotted lines on Fig. 1) by a. finger 33 pivoted on a block 34 which is splined upon the shaft 28 so that while capable of being moved along the shaft it will be rotated thereby. From second position the fillers are pushed to third position (indicated by dotted lines 35, Fig. 1) by a finger 36 pivoted on a block 37 which is splined upon the shaft 28. Each of these fingers 33 and 36, as seen in Fig. 3, comprises a member 38 designed to engage the edges of the fillers near the backs, and a member 39 adapted to engage the edges of the fillers further away from the backs and they are retained in normal position by springs 40. The lingers are connected by a rod 41 and the blocks are connected to a shaft 42 so that they will move together along the shaft 28 and will also swing in and out together as this shaft is turned.

Movable along the shafts 28 and 29 is a frame 43. This frame carries a air 0 rotary shafts 44 to which jaws 15 are c amped, Fig. 5. The shafts 44 are connected by intermeshing toothed segments 4-6, one of which has a rocker arm 47 that is connected by a link 48 with a rocker arm -19 that is splined on the shaft 28, 7, so that the rotary movements of the shaft 28 will cause the jaws to open and close. These jaws are so located and they are so reciprocated and oscillated with the pusher fingers that they grip the fillers at the joints underneath the backs as shown in Fig. 5, and carry the fillers assisted by the pusher finger 36 from second position to third position.

' Also mounted on the shafts 44: carried by the frame 43 are clamping jaws 50, Fig. (3. These jaws are opened and closed by the turning of the shafts 4-1, and they move back and forth with the frame -13 in such manner as to engage the fillers at the joints and carry them from third position onto the saddle plates 1. Movable with the frame is a finger 51 that is yieldingly mounted in an arm 52 which is fastened to a bushing 53 keyed to the shaft 28, Fig. 6. This last mentioned finger is so located and operated that it is back of the edges of the fillers when they are on the saddle and prevents them from being drawn backward should they tend to adhere to the clamp jaws.

The fingers swing in back of and the clamps close on the respective fillers and move forward together to carry the fillers from station to station, and then the fingers swing out and the clamps open together and return for the following fillers, the mechanisms for causing the synchronous reciprocation and oscillation of these members being similar to those fully set forth in the patent before referred to.

The feed mechanism herein described is of particular advantage when fillers with uncut edges, or with rough nntrinimed edges. or with gilded or stained edges are being fed. As the separator plate extends from the front of the machine to the saddle, the uncut, or
